Description

Technical Field

[0001] This utility model belongs to the field of PCB board processing technology, and specifically relates to a flipping mechanism for PCB board processing. Background Technology

[0002] A PCB board flipping mechanism is a special flipping device used in the PCB board (printed circuit board) processing process. Its main function is to flip the PCB board to be processed from its initial position to another position so as to perform double-sided or multi-sided processing. The PCB board flipping mechanism is one of the important pieces of equipment on the PCB board production line. It achieves precise flipping and positioning of the PCB board through a specific mechanical structure and control system.

[0003] However, traditional PCB board processing flipping mechanisms usually require manual clamping, positioning, and rotation operations, which increases the complexity and difficulty of the operation. Operators need to spend more time and effort to ensure the accuracy and stability of the processing. Traditional devices can often only adapt to PCB boards of fixed or limited sizes. When processing PCB boards of different sizes, it may be necessary to replace the entire clamping mechanism or adjust the equipment, which is not only time-consuming and labor-intensive, but may also interrupt the production process and reduce production efficiency.

[0004] To address this issue, a flipping mechanism for PCB board processing is designed. Utility Model Content

In addition to size adaptability, the clamping mechanism is also designed to accommodate PCB board shapes. By adjusting the layout of the clamping points and controlling the clamping force, the mechanism can clamp PCB boards of various shapes, further expanding its application range. The clamping mechanism can rotate the PCB board at a specified angle, meeting the requirements for double-sided PCB board processing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown;

[0026] A flipping mechanism for PCB board processing includes a mounting base plate 1.

[0027] In this implementation plan: Traditional devices usually require manual clamping, positioning, and rotation operations, which increases the complexity and difficulty of the operation. Operators need to spend more time and effort to ensure the accuracy and stability of the processing. Traditional devices can often only adapt to PCB boards of fixed or limited sizes. When processing PCB boards of different sizes, it may be necessary to replace the entire clamping device or adjust the equipment. This is not only time-consuming and labor-intensive, but may also interrupt the production process and reduce production efficiency. To solve this technical problem, a clamping mechanism 2 is added on this basis.

[0028] Furthermore:

[0029] like Figures 1 to 5 As shown:

[0030] Based on the above: The clamping mechanism 2 includes a lifting cylinder 21, a connecting plate 22, and a mounting box 23. The lifting cylinder 21 is mounted on the upper surface of the mounting base plate 1. The connecting plate 22 is fixedly connected to the outer side of the top of the lifting cylinder 21. The mounting box 23 is fixedly connected to one side of the connecting plate 22. A rotating box 24 is fixedly connected to one side of the mounting box 23. A connecting rod 25 is connected to one side of the rotating box 24 via a rotating mechanism. A mounting frame 26 is fixedly connected to one side of the connecting rod 25. Rotating arms 27 are rotatably connected to both sides of the mounting frame 26. A slider 28 is slidably connected to the outer side of the end of the mounting frame 26. First limiting posts 29 are fixedly connected to both sides of the slider 28. A clamping frame 210 is fixedly connected to one side of the slider 28. Two telescopic rods 212 are mounted on one side of the connecting rod 25. A limiting plate 211 is fixedly connected to the outer side of the end of the telescopic rod 212. Limiting plates 211 are fixedly connected to the outer sides of both ends of the limiting plate 211. The outer side of the second limiting post 213 contacts the inner side of one end of the rotating arm 27, and the outer side of the first limiting post 29 contacts the inner side of the other end of the rotating arm 27. The rotating mechanism includes a rotating component 214 and a rotating disk 215. The rotating component 214 is rotatably connected to one side of the rotating box 24. The outer side of the middle part of the rotating component 214 is fixedly connected to one side of the connecting rod 25. The rotating disk 215 is provided above the rotating component 214. The motor 218 is installed inside the mounting box 23. The outer side of the main shaft of the motor 218 is fixedly connected to one side of the rotating disk 215. A toggle rod 216 is fixedly connected to one side of the rotating disk 215. A toggle post 217 is fixedly connected to the outer side of one end of the toggle rod 216. Four rectangular through slots are provided at the end of the rotating component 214. The outer side of the toggle post 217 contacts the inner side of the rotating component 214. Multiple through holes are opened on the outer side of the clamping frame 210.

[0031] In this implementation scheme: When using the device, the user can place the PCB board to be clamped and fixed between the two clamping frames 210. At this time, the user can adjust the height of the connecting plate 22 through the lifting cylinder 21. The user can then activate the telescopic rod 212, which shortens its length and moves the limiting plate 211 inside the mounting frame 26. Simultaneously, the second limiting post 213 drives the rotating arm 27 to rotate. As the rotating arm 27 rotates, it clamps the two sliders 28 towards the center through the first limiting post 29, thereby fixing the PCB board through the clamping frame 210. This can accommodate different sizes. At this time, the user can activate the motor 218, which drives the rotating disk 215 on the outside of its main shaft to rotate. As the rotating disk 215 rotates, it drives the toggle lever 216 on one side of the rotating disk 215 to rotate. At the same time, the toggle lever 217 and the toggle lever 216 rotate. The rotating component 214 contacts the through slot on its inner side, thereby driving the rotating component 214 to rotate the PCB board at a specified angle, which facilitates operation. The through holes in the clamping frame 210 can be used for ventilation. The clamping mechanism 2 adopts an adjustable clamping design, which can clamp PCB boards of different sizes. This means that it can provide stable clamping for various sizes without frequent replacement or adjustment of the clamping device, thereby improving production efficiency. In addition to size adaptability, the design of the clamping mechanism 2 can also take into account the adaptability to the shape of the PCB board. By adjusting the layout of the clamping points and controlling the clamping force, the mechanism can clamp PCB boards of various shapes, further expanding the application range. The clamping mechanism 2 can drive the PCB board to rotate at a specified angle, such as 90 degrees, which meets the needs of double-sided processing of PCB boards. There is no need to manually flip the PCB board, reducing labor intensity and improving processing efficiency.

[0032] Furthermore:

[0033] In an optional embodiment, a buffer strip 219 is fixedly connected to the inner side of the clamping frame 210, and the buffer strip 219 is made of rubber.

[0034] In this implementation scheme: the buffer strip 219 has soft and elastic properties, which can provide cushioning during the clamping process and prevent the clamping frame 210 from directly contacting the PCB board surface, thereby effectively preventing damage such as clamping marks and scratches, protecting the integrity and aesthetics of the PCB board. The buffer strip 219 can increase the friction between the clamping frame 210 and the PCB board, making the clamping more secure. Even during rotation or complex processing, it can ensure that the PCB board will not fall off or shift due to vibration or external force, thus improving the stability of the processing.

[0035] Working principle: When using this device, the user can place the PCB board to be clamped and fixed between the two clamping frames 210. At this time, the user can adjust the height of the connecting plate 22 through the lifting cylinder 21. The user can then activate the telescopic rod 212, which shortens its length, causing the limiting plate 211 to move inside the mounting frame 26. Simultaneously, the second limiting post 213 drives the rotating arm 27 to rotate. As the rotating arm 27 rotates, it clamps the two sliders 28 towards the center through the first limiting post 29, thus allowing the PCB board to pass through the clamping frame 210. Ten PCB boards are fixed together to accommodate different sizes. The user can then start the motor 218, which drives the rotating disk 215 on the outer side of its main shaft to rotate. Simultaneously, the rotating disk 215 rotates, causing the actuating lever 216 on one side of the disk to rotate as well. The actuating post 217 contacts the through groove on the inner side of the rotating component 214, thereby driving the rotating component 214 to rotate the PCB board at a specified angle, facilitating operation. The through holes in the clamping frame 210 allow for ventilation. The clamping mechanism 2 uses an adjustable clamping design. The design allows for clamping PCBs of different sizes, meaning stable clamping can be provided for various sizes without frequent changes or adjustments to the clamping device, thus improving production efficiency. In addition to size adaptability, the design of the clamping mechanism 2 can also be adapted to the shape of the PCB. By adjusting the layout of the clamping points and controlling the clamping force, the mechanism can clamp PCBs of various shapes, further expanding its application range. The clamping mechanism 2 can rotate the PCB at a specified angle, such as a 90-degree flip, which meets the needs of double-sided PCB processing. It eliminates the need for manual flipping of the PCB, reducing labor intensity and improving processing efficiency. The buffer strip 219 has soft and elastic properties, which can provide cushioning during clamping and prevent the clamping frame 210 from directly contacting the PCB surface, thereby effectively preventing damage such as clamping marks and scratches, protecting the integrity and aesthetics of the PCB. The buffer strip 219 can increase the friction between the clamping frame 210 and the PCB, making the clamping more secure. Even during rotation or complex processing, it can ensure that the PCB will not fall off or shift due to vibration or external force, improving processing stability.
